Аннотация
New inhibitors of Ca2+ and calmodulin-dependent cyclic-nucleotide phosphodiesterase, KS-501 and KS-502 were isolated from a fungus, Sporothrix sp. KAC-1985. Inhibitory concentration causing 50% inhibition (IC50) values of KS-501 and KS-502 for bovine brain enzyme were 1.8 and 4.3 microM, respectively. The compounds exhibited no or weak inhibition for calmodulin-independent cyclic-nucleotide phosphodiesterases and protein kinase C.
